Resynchronization
After replacing the battery in your transmitter, or if
only the instant alarm works, the transmitter needs to be
resynchronized to the receiver. Do this by pressing and
holding both the button with the lock symbol and the
button with the unlock symbol at the same time for
about eight seconds. You must be within range of
the vehicle.
Once the transmitter has been resynchronized, the horn
will chirp and the exterior lamps will flash once. The
system should now operate properly.
Trunk
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
trunk lid:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on any airflow selection except RECIRC.
That will force outside air into your vehicle.
See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

2-39
As you signal a turn or a lane change, if the arrows flash
at twice the normal rate, this may indicate that a signal
bulb may be burned out and other drivers won't see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will flash even if a
turn signal bulb is burned out. Check the front and rear
turn signal lamps regularly to make sure they are
working. You do not need to add a different flasher.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or
high to low, pull the turn signal lever toward you, then
release it.
When the high beams are
on, a light on the instrument
panel cluster will also be on.
If your vehicle is equipped
with HUD, this light
will also appear in the
display area.
Flash-to-Pass Feature
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass. It
works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are off or on low beam, your
high
-beam headlamps will turn on. They'll stay on as
long as you hold the lever toward you and the
high
-beam indicator on the instrument panel cluster
comes on. Release the lever to turn the high
-beam
headlamps off.

Safety Belt Reminder Light
When the key is turned to RUN, a chime will come
on for about eight seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds, then
it will flash for about
55 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.

4-39 Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider
turns than normal. Do this so your trailer won't
strike soft shoulders, curbs, road signs, trees or other
objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your dealer. The arrows on your instrument panel
will flash whenever you signal a turn or lane change.
Properly hooked up, the trailer lamps will also flash,
telling other drivers you're about to turn, change lanes
or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It's important
to check occasionally to be sure the trailer bulbs are
still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle's lighting
system, its bulb warning lights may not let you know if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they're all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if one
of your vehicle lamps is out.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
caused by electrical problems.
Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
There are three fuse blocks in your vehicle: the
instrument panel fuse block located under the instrument
panel, the underhood fuse block located in the engine
compartment on the passenger's side of the vehicle and
the rear fuse block, located under the rear seat.
